This species is distinguished by the following characters: median predorsal scales 6-8 (usually 7); 3 scale rows on cheek, 1(6-7), 2(6-9), 3(2-5); pectoral-fin rays 13-15 (usually 14); conical teeth on side, none in female, usually 2 on upper dental plate for terminal male; lips mainly covering dental plates; caudal fin rounded in small female, with prolonged lobes in large adult. Colour of male reddish brown anteriorly with red upper lip and dark bands around the mouth, greenish posteriorly with dark scale margins, the markings in the head variable but always with a dark-edged yellowish or bright green dot or spot at top end of line from mouth through eye to top of opercular opening.; female red on head, belly and fins, side with wavy black and white stripes, and dark green bands around mouth and eye (Ref. 9793, 90102).
